derivations: Restore UTF-8 encoding of build scripts.

Reported by Mark H Weaver <mhw@netris.org>
at <https://lists.gnu.org/archive/html/guix-devel/2017-04/msg00457.html>.

* guix/derivations.scm (build-expression->derivation): Use a string
output port for the expression.  This reverts part of
2dce88d5bb.
* tests/derivations.scm ("build-expression->derivation and builder
encoding"): New test.
